Anyone else experiencing audio drop outs and lip sync problems with Directv? I just switched from Dish Network to Directv and am having these problems. It doesn't matter if it is coax or optical digital output on my new Samsung SIR-TS160 HD receiver. I notice the lip sync problem also on my second cheap receiver (Uniden UDS100) so it must not be the reciever. I asked Directv about the lip sync problem and they told me they have never heard of the problem. What gives.
